SWITCH-STAND LOOK.

To all whom it may concern:

Be it known that 1, CHARLES 001), a citizen of the United States, residing at Moul' ton, in the county of Appanoose and State of Iowa, have invented a new and useful Improvement in Switch-Stand Locks, of which the following is a specification.

My invention is an improvement in switch stand locks, and has for its object the provision of a simple, inexpensive device of the character specified, capable of being applied to existing stands without radical change, by means of which, the dropping of the operating lever into inoperative position after setting the switch to either position will positively lock the switch, that is will lock the operating lever to the stand.

In the drawings, Figure 1 is a perspective view of the improved lock. Fig. 2 is a transverse vertical section, and Fig. 3 is an end view of the look.

In the present embodiment of the invention the stand is of any usual construction, having the table 1 provided with spaced notches 2 and 3, for receiving the operating lever 4, which is pivoted at its inner end to the arm 5 of the switch rod or shaft 6. The arm 5 is provided with a notch 7 for receiving the inner end of lever 4e, and the lever is pivoted to the arm 5 by means of a bolt 8. When the lever is swung into horizontal position, the inner end thereof fits the notch 7, and the lever is by the same movement released from notch 2 or 3, so that the switch rod may be turned.

An angle plate 91O has its horizontal portion 9 secured to the upper face of the arm 5, in such manner, that one face of the vertical portion 10 of the plate is in alinement with one wall of the notch 7. The body 11 of a padlock is held by the plate, in position to receive the shackle 12 of the padlock, which is held by lever 1, when the lever is in inoperative position. The body 11 of the padlock is secured to the portion 10 of the plate-9-10 by means of a link 13, arranged on the opposite side of the body from the portion 10, and connected to the said portion by means of bolts let and 15. The link 13 is of greater length than the width of the body, extending beyond the Specification of Letters Patent.

body at both ends of the link, and the bolt 14 is passed through the inner end of the link and the portion 10 of the plate 9-1O while the bolt 15 is passed through the outer end of the link and the said portion 10. As an additional holding means, a bolt 25 is passed through the portion 10 of the plate 910 and the lug 2 1 of the body. The shackle 12 is secured to the reduced upper or inner end 16 of the lever 4-, by means of a link or strap 17. The said link is 0011- nected to the end 16 of the lever by means of a bolt 18. The link is engaged in a longitudinal slotor opening 19 in the portion 16, and the bolt 18 passed transversely of the said slot or opening through the end of the strap or link as shown in Fig. 2. The opposite end of the link 17 is connected to the shackle by means of a bolt 20, and the shackle is hinged to the body of the padlock in the usual manner as shown in Figs. 1 and 2. The link 13 on the body is arranged above the keyhole 23, so that the said link will not interfere with the in sertion of a key. The body 11 of the padlock is provided with the usual perforated lug 24, for receiving one end of a chain. The said lug is however engaged by a bolt 25, instead of the chain, the bolt engaging also the portion 10 of plate 910. The body 11 of the padlock is held in position to receive the bolt 26 of the shackle 12, when the lever l is engaged with notch 2 or 3, and as the class of padlocks are spring locks, the mere act of dropping the lever into inoperative position also looks the switch, by engaging bolt 26 of shackle 1,2 with the body 11.

In operation, when the lock 11- 12 is unlocked by the usual key, lever 4. may be lifted into horizontal position to operate the switch. After the switch has been thrown into either position, the dropping of lever 4 into inoperative position also looks the lever in such position. The element of human error is thus eliminated, that is so far as failure to lock the switch is concerned. lVhen the switch has been returned to normal position, the operating lever is released, and drops into one of the notches of the stand. The releasing of the lever locks the lever to prevent it from disengagement with the notch.

It will be noted that the entire padlock is carried by the arm 5, and that the switch is locked in either main line or siding posi tions. The lever is not only locked from being moved into alinement wit-h arm 5, that is from movement into horizontal position, but is also looked in the notch of the table.

I claim:
